CONVERT DF ADDENDUM

This function allows the user to convert the addendum which is generated by other CAD software to the addendum that eta/DYNAFORM recognizes. The user can directly modify the addendum by using the tools in eta/DYNAFORM environment. The included auxiliary functions for convenient conversion are: MODEL CHECK / REPAIR, INNER FILL, MORPH BY LINE and ADD… TO PART. The dialog box of Convert DF Addendum is illustrated in Figure 6.4.1.

 

l   MODEL CHECK / REPAIR

This function allows the user to check and repair the addendum mesh before or after conversion. Refer to Section 5.5  for detailed description about the check/repair functions.

 

l   INNER FILL

This function is used to fill the inner hole of the trimmed binder, as shown in Figure 6.4.2. Refer to Section 6.1.4.1  for detailed description about this function.

l   MORPHING HOLE FILL

This function is used to edit the filled inner hole of binder by adding control lines. After clicking on this button, the program displays a dialog box as illustrated in Figure 6.4.3. The user can select TANGENT to make sure that the generated surface boundary after editing is tangent to the binder. Click ADD to add control lines, EDIT to edit control lines, REMOVE to remove control lines, PREVIEW to preview the generated inner hole surface of binder after editing. The operation of this dialog box is similar to the one in Section 6.2.3 Modify Binder.

l   ADD… TO PART

This function allows the user to move line, element or surface from one part to another. The user can enter part name manually to create a new part. Refer to Section 4.4  for detailed description about this function.

 

l   DEFINE ORIGINAL PART

The DIE and BINDER must be defined prior to creating addendum. This function enables the user to assign the original part(s) as DIE using the SELECT PART function. If the user has defined the DIE using DEFINE TOOLS function in TOOLS menu, this button is disabled. As illustrated in Figure 6.4.4, the user selects the red part as the original part.

 

l   DEFINE BINDER PART

This function enables the user to assign BINDER using the SELECT PART function.  As illustrated in Figure 6.4.4, the user selects the green part as the BINDER.

 

l   SELECT ADDENDUM ELEMENTS

This function enables the user to select all the elements of original addendum design. The function provided in SELECT ELEMENTS dialog box is utilized to conduct the operation. As illustrated in Figure 6.4.4, the user selects all elements in the blue part as the addendum part.

APPLY

This function is used to convert the original addendum to the addendum in DFE environment. eta/DYNAFORM creates the new addendum in the original position. A typical result is illustrated in Figure 6.4.5.
